FORMING CELL-CASES.

To all whom it may concern: 7

Be it known that I, GEORGE PAYNE, a'subject of the Kingdom of Great Britain, residing at 16 New Bartholomew street, Birmingham, in the county of Warwick, England, have invented a. certain new and useful Method of Forming Cell-Cases, of which the 7 following is a specification.

This invention relatesto the packing of small articles, and which is particularly applicable in the case of small coiled springs,

whichif not separatedfrom' each other in the packing are liable to become entangled and damaged, while the disengaging of the one from the other when required for use necessitates a considerable amount of'time V which is wasted, the arrangement also being corrugating paper of sufficient stiffness, this,

being effected in a suitable plate or board having grooves into which the paper 1s forced by sheet metal pressers, after which the partitions are cut through transversely to allow of the insertion of lateral strips of stiff paper or thin cardboard, the plate or .cuts for enabling the longitudina board being provided with grooves or saw such transverse cutting of partitions, and the insertion of the strips tobe effected, the whole being secured together and stiffened by pasting or gumming a stiff sheet of paper or thin cardboard over the whole of the back of the receptacle thus formed.

In order that this invention may be clearly understood and readily carried into practice, reference may be had to-the appended sheet of drawings, upon which Figure 1 is a view-of the device for effecting the packing of articles, such View being shown in section at one end.

Fig. 2 'is a viewof a board suitable for. effecting the; manufacture of the, packing device. v v

Fig. 5, is a similar longitudinal section to able board, such board bein provided with a series of cuts b of suficient width to allow of a knife being drawn through same. Strips of paper or cardboardd of suitable stiffness and depth are then inserted into the cuts, thus forming a series of square or'oblong receptacles 0 both laterally and longitudinally divided from each other, a sheet of paper or cardboard f of suitable stiffness being adhesively secured over the whole surface which forms the bottom of the receptacles prior to the arrangement being removed from the plate.

By this means the whole of the reverse side of thedevice to that to which the sheet of paper or cardboard f is adhesively at- -tached isprovided with a series of receptacles or recesses e which are 1n parallel rows both longitudinally and laterally, and into each of which recesses or receptacles e' the articles to be packed can readil be inserted or removed, and are kept entirely separate from contact with each other.

Theftransverse cuts b are of less depth than the grooves b in which the longitudinal partitions are formed, so that when the' knife is drawn through the transverse cuts 6 of the board, a small portion of thelongitudinal partitions a at the bottom is not severed, the strips (l in such case being slightly less; in depth than the depth of the recess.

The board 6 as shown in Fig. 2, is one in which a series of three packing devices,

paper into the grooves b formed'in a suitsuch as illustrated in Fig. 1, can be made by onefprocess, such devlces being severed from each other at b, the process of forming the device being as follows A strip of paper of the, required stiffness, width and length is placed upon the board I) and held in position at one end while the corrugation is effected by forcing the paper into the first groove by "a sheet metal 7c is then withdrawn and the flange m of a similar presser such as m is. inserted to re tainthe paper in the groove 1) into which it has been pressed, while the flange 70 of the presser 7c is caused to force the paper into the next groove, and so on, step by step into each groove of the board.

The strip of wood or cardboard p which is marked at p with the positions of the cuts 6 is then placed on the board at the one end of the paper, and a sharp knife is drawn along irom one end to the other of the saw cuts 6 thus'cutting through the paper and the partitions a, after which the strips of paper or cardboard (Z are inserted into the respective cuts, such strips being of a suitable length for each of the series of devices which are being formed on the board. The sheet of paper or cardboard f of suitable stiffness being then adhesively secured over the whole surface, after which the device can be withdrawn from the grooves and saw cuts in the form illustrated by Fig. 1.

The material from which the corrugations forming the partitions, as also the division strips and backing are made may be varied, solong as that for the corrugations is sufiiciently flexible to allow the partltions to be fOljmed and is capable of being readily out.

What I claim as my invention and desire to secure by Letters Patent is The method of making a compartment package, consisting in placing a sheet of 7 material on a forming board having spaced grooves in its face and also having grooves lntersectlng the first named grooves pressing the material into the first named grooves to form spaced ridges in the same, cutting grooves transversely across said ridges by means of a tool guided in the second named grooves of the forming board, inserting strips of material in said second named grooves and in the cuts in the ridges while the said ridges are in the said first named grooves, and securing a reinforclng sheet on the first named sheet and while the ridges of said first named sheet and said strips are in the grooves of the forming board, so that said reinforcing sheet extends across the outer edges of said strips.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

GEORGE PAYNE.
